If this noise occurs after shutting off a fixture (e.g., shower or sink), I'd pop the lid on the toilet tank and check there. Sometimes, this type of noise occurs when water pressure is reduced somewhere else, causing the fill valve to open slightly and howl like a foghorn. So, after shutting off the water and hearing the noise, pull up on the toilet tank float to see if it stops. If it does, replacing the fill valve will fix it.if still problem persist call for Plumbing repair service.
